Hi, I'm creating a time-lapse script where I take many pictures with esp32-cam throughout the day and I intend to upload them to a local ftp server in the evening. I recall that uploading many files is slower than uploading one single big file (provided the total size is the same). It seems there're...

May be I've taken wrong approach? Because when I plug the esp8266 I don't know what byte will be first caught by the UART, I'm reading one byte from UART until that byte is the data frame start (0xff), then I read the immediate next 3 other bytes. That's why I can't access all bytes as the same time...

Thank you, guys!
I'm now getting somewhere by dividing individual bytes with hex() and parsing the dataframe

I thought every byte should start with \x. Do you mean that e.g. this bytearray - b'\xff\x08kr' has valid 4 bytes in it? If that's the case, how do I separate each individual byte for further processing?

Hi, I've got a general question. I'm reading a serial sensor which is suppose to produce a data frame of 4 bytes(always starting with 0xff and the last 4th byte being the checksum). I've got problems with detecting a valid data frame because some of the bytes are just garbage. My question is how do ...

All works now. I forgot to base64 encode the attached image

I've got this strange picture, when using the driver. Does anyone know what could cause this? My module seems to be the same as the one the driver author was using (judging by the picture in the repo). I'm emailing the picture as a attachment, using this uMail https://github.com/shawwwn/uMail cam.jp...

It seems there is one from a couple of weeks Just found it and I'm about to test it.

Hi, I'm using @deshipu driver https://bitbucket.org/thesheep/micropython-vl53l0x/src/default/ for this time of flight sensor. All working fine, except it measures always in "normal mode" where the max distance measured is 1.2m-1.3m. The datasheet https://www.st.com/resource/en/datasheet/vl53l0x.pdf ...

Hi Peter and Kevin, great stuff and documentation as usual! Have you tried to make the server run on esp8266 as well?
